libcamera: v4l2_subdevice: Change V4L2Subdevice::Whence
The V4L2Subdevice::Whence enumerations defines two values that should
correspond to the V4L2_SUBDEV_FORMAT_ACTIVE and V4L2_SUBDEV_FORMAT_TRY
definitions.
The V4L2 symbols are defined as:
V4L2_SUBDEV_FORMAT_TRY = 0,
V4L2_SUBDEV_FORMAT_ACTIVE = 1,
While the libcamera defined enumeration is:
enum Whence {
ActiveFormat,
TryFormat,
}
As V4L2Subdevice::Whence values are used to populate data types
defined in v4l2-subdev.h used as arguments to VIDIOC_SUBDEV_*
ioctls, the V4L2Subdevice class is required to adjust their value as:
subdevFmt.which = whence == ActiveFormat ? V4L2_SUBDEV_FORMAT_ACTIVE
: V4L2_SUBDEV_FORMAT_TRY;
Drop the adjustment by defining :
Whence::TryFormat = V4L2_SUBDEV_FORMAT_TRY;
Whence::ActiveFormat = V4L2_SUBDEV_FORMAT_ACTIVE;
